Bluetooth is smaller profile but most apps seem to have issues with them. I have a wifi version and it's slightly bigger than I would like but you can do a OBD2 splitter and hide it easily. I can't remember the app I use but can tell you after I get off work. Not sure what causes the issue but I tried to use an older iPhone 3GS and it constantly dropped the wifi signal my iPhone 5C does not. Great tool for resetting codes, checking codes among other features.
